The Large Span Cable Ladder gives you the best of both worlds. It has the open design of a ladder tray. This lets heat escape from your cables. It also makes the cables easy to see and access. At the same time, it has the structural strength needed for long spans. The rung spacing is 250mm, which is tighter than standard ladder trays. This reduces the load on each individual rung. The overall load capacity increases significantly.
Thicker Side Rails and Patented Joints
We build this ladder tray with thicker side rails. This increases resistance to bending. The connection between the rungs and the side rails is a special focus area. We use triangular reinforcement plates at every joint. This is our patented design. It prevents weld cracking under heavy loads. We also add integral stiffeners along the side rails. These act like miniature support beams. Every part of the Large Span Cable Ladder works together to resist deflection. Under a 6-meter span with a 3.0kN/m load, the deflection stays under 30mm. After we remove the load, the ladder returns to its original shape. No permanent deformation.
Built for Highways, Pipe Galleries, and Factories
The Large Span Cable Ladder is used in many demanding applications. You see it in highway tunnels. It runs through industrial pipe galleries. It spans across large factory floors. We offer materials for every environment. Q235 steel with powder coating is the indoor standard. Hot-dip galvanized steel is for outdoor or moist areas. Stainless steel is for corrosive environments like chemical plants. Aluminum is for weight-sensitive applications. All accessories are built to the same heavy-duty standard. We include splice plates, support brackets, and drop rods. Everything matches the capacity of the ladder tray. Our 2-year warranty and support give you confidence.
